DETAILED DESCRIPTION OF THE INVENTION

In the following description, numerous specific details are set forth inorder to provide a more thorough description of the present invention.It will be apparent, however, to one skilled in the art, that thepresent invention may be practiced without these specific details. Inother instances, well-known features have not been described in detailso as not to obscure the invention.

In general, the tray table herein provides a versatile support for oneor more portable electronic devices. As will be described further below,the tray table may be configured to hold portable electronic devices ofvarious shapes and sizes. This is advantageous in that it allowspassengers to enjoy use of their personal electronic devices during aflight. air or other vehicular travel. For example, passengers mayaccess and enjoy various media or other entertainment via theirelectronic devices during a flight, road trip, cruise, or bus or trainride. Using the tray table, passengers avoid having to hold, prop up, orotherwise secure their electronic devices in unorthodox ways, such as byleaning the devices against various surfaces at their seats. Inaddition, the tray table increases passenger comfort by holding portableelectronic devices in an ergonomic position. In some embodiments, aswill be described further below, the tray table's support may berotatable or movable to allow adjustments to the position of a portableelectronic device.

FIG. 1A provides a top perspective view of an exemplary tray table 104having a support 108 for portable electronic devices. As can be seen,the tray table 104 provides a planar top surface 112 that passengers mayplace their various items on. The tray table 104 may also include one ormore mounting points 116 or mounts that allow it to be installed in anaircraft, such as on a back portion an aircraft passenger seat. Intypical embodiments, the tray table 104 will mount to the rotatable traytable support arms of aircraft passenger seats. Mounting points may beat or near a back end 120 of the tray table 104. The mounting points 116will typically allow the tray table 104 to rotate or otherwise move soas to allow the tray table to be moved between a stowed position (whereit is secured to a seat back) and a service position (where it issubstantially horizontal to support items on its top surface).

As can also be seen, the support 108 may be positioned at the back end120 of the tray table 104. This allows the portion of the top surface112 in front of the support 108 to be used even when the support 108 isin use. It is contemplated that the support 108 may be located atdifferent locations as well. For instance, the support 108 may be near afront end 124 of the tray table 104, at a central portion 128, orelsewhere. Typically, the support 108 will extend laterally across thetray table 104 parallel to the back edge of the tray table, however itis contemplated that the support 108 may be angled slightly in someembodiments.

In one or more embodiments, the support 108 may be an excavated portionof the tray table 104 configured to accept a portable electronic device.For instance, the support 108 may be a cavity 132 formed in the body 136of the tray table 104 for instance. For example the cavity 132 may be aslot or groove. The cavity 132 may comprise a front wall 140 and a backwall 144, and one or more sidewalls 148.

It is noted that the tray table 104 may include one or more magnets 164at or near its top surface 112 to hold a portable electronic device onthe top surface. In operation, the magnets 164 would be attracted to amagnetic structure within the portable electronic device, thus holdingthe portable electronic device. Though shown at particular locations inFIG. 1A, it is contemplated that the magnets 164 may be at variouslocations of the tray table 104. In addition, fewer or additionalmagnets 164 may be provided in one or more embodiments.

FIGS. 1B-1C provide cross sectional views of the tray table 104 andsupport 108. FIG. 1B is a cross sectional view across Line 1, while FIG.1C is a cross sectional view across Line 2. As can be seen, the cavity132 may have a bottom 152 to provide support to a portable electronicdevice thus preventing the device from sliding out of the support 108through its bottom. It is noted that the bottom 152 may have one or moreopenings 156 to allow ventilation and to allow any spilled liquids orother debris to fall out of the support 108. This aids in keeping thesupport clean.

It is contemplated that the support 108 may be configured to provideconnectivity to any device it is holding. For instance, in oneembodiment, the support 108 may optionally include an electrical,optical, or other connectors 168 to provide power or data connectionsfrom a power or data source to a portable electronic device. If aconnector 168 is provided, it is contemplated that one or more magnetsmay optionally be used to secure a connector 168 to a portableelectronic device. In some embodiments, the support 108 may providewireless connectivity for power transmission or data connections. Forexample, the support 108 may provide inductive battery charging or ashort-range data connection (such as a Bluetooth™ connection) toportable electronic devices via one or more coils 176 or antennas. Thetray table 104 may contain its own power source, such as one or morebatteries 180, and/or may be connected to an aircraft's power system.The batteries may be rechargeable. In one or more embodiments, thebatteries may be held in a compartment within the tray table 104 and beremovable therefrom, such as for replacement, recharging, or both.

FIG. 1D illustrates a cross sectional view of an additional embodimentof the support 108. As can be seen, the cavity 132 may be “L” shapedthus providing a bottom 152 to support a portable electronic device. Thelower portion of the “L” shape terminates at an opening near the backend of the tray table 104. This is advantageous in that it causes anyfluids (or other dirt/debris) to flow toward the back of the tray table.In the event of a spill, such fluids would exit the tray table 104 awayfrom the passenger as much as possible. It is noted that rather thanforming the entire cavity 132 into an “L” shape, one or morechannels/openings, could form the bottom of the “L” shape and guidefluids (or other dirt/and debris) toward the back of the tray table.

It is contemplated that a removable liner may be provided in someembodiments to aid in keeping the support clean. The liner may conformto the cavity 132 and may removed and replaced with a new liner whendirty. Alternatively or in addition, a plug, cap or other or coveringmay be provided to fill the cavity 132 to prevent dirt or debris fromentering the support 108. Typically, the plug or cover would have aplanar top positioned flush with the top surface 112 of the tray table104, when inserted into the cavity 132. It is contemplated that the plugor cover may be affixed to the cavity 132 in some embodiments. Forinstance, the plug or cover may be a spring loaded or other biasedmechanism that may be depressed downward to provide access to the cavity132, thereby allowing an electronic device 204 to be inserted into thesupport 108. When not depressed, the biasing mechanism would raise theplug or cover such that it is flush with the top surface 112 of the traytable.

Referring to FIG. 1B, the support 108 may be angled in one or moreembodiments. For instance, the support 108 may have a back wall 144and/or front wall 140 that is at a non-perpendicular angle to the topsurface 112 or body 136 of the tray table. As will be described furtherbelow, this allows the support 108 to hold a portable electronic deviceat an angle, which causes the device to face a seated passenger forideal viewing. In one or more embodiments, the support 108 will beangled rearward towards the back end or edge of the tray table 104 toaccomplish this.

It is contemplated that the cavity 132 may have various other crosssectional shapes as well. For example, the front wall 140 and back wall144 may form a “V” or other shape that tapers from the top surface 112of the tray table 104. This allows portable electronic devices ofvarious thicknesses to be inserted into and securely held by the cavity132. Alternatively or in addition, the cavity 132 may have a steppedcross section to produce a set of discrete widths between the front wall140 and back wall 144. In other words, the front wall 140 and/or backwall 144 may be shaped like steps. This also allows portable electronicdevices of various thicknesses to be supported by the cavity 132.

FIG. 1E is a bottom view of the tray table 104 showing the opening 156,which allows dirt and debris to exit the support 108. As can be seen,the opening 156 extends to the bottom surface 160 of the tray table 104so that dirt and debris can fall out of the tray table 104. The opening156 will typically be smaller than the cavity 132 so that an electronicdevice may be supported therein without falling through the opening. Forexample, the opening 156 may have a smaller width and/or length than thesupport 108. Though shown as a single opening 156 in FIG. 1E, it iscontemplated that a plurality of openings may be used.

In addition, an opening 156 may be formed in various shapes and sizes.For example, an opening may have a length of 1-2 inches in someembodiments. This is advantageous in that such opening 156 is largeenough to allow dirt and debris to escape while not being so large as toresult in a smaller electronic device (such as a phone or other handhelddevice) to fall through the opening. In one or more embodiments, thebottom 152 of the support 108 may slant towards the opening 156 so as toguide dirt and debris toward the opening.

In one or more embodiments, the body 136 may be constructed to aid incleaning the tray table 104. For example, the body 136 or portionsthereof may be formed from material having anti-microbial oranti-bacterial qualities. In some embodiments, the body 136 or portionsthereof may be coated with such materials. It is noted that onlyportions of the tray table 104, such as the top surface 112 may beformed from or coated with anti-microbial and/or anti-bacterialmaterials.

It is contemplated that a removable liner may be provided in someembodiments to aid in keeping the support clean. The liner may conformto the cavity 132 and may removed and replaced with a new liner whendirty. Alternatively or in addition, a cover 172, cap or other orcovering may be provided to fill the cavity 132 to prevent dirt ordebris from entering the support 108. Typically, the cover 172 wouldhave a planar top positioned flush with the top surface 112 of the traytable 104, when inserted into the cavity 132, such as shown in FIG. 1F.FIG. 1F is a top view of an exemplary tray table 104 having a support108. It is contemplated that the cover 172 may be affixed to the cavity132 in some embodiments. For instance, the cover 172 may be a springloaded or other biased mechanism that may be depressed downward toprovide access to the cavity 132, thereby allowing an electronic device204 to be inserted into the support 108. When not depressed, the biasingmechanism would raise the cover 172 such that it is flush with the topsurface 112 of the tray table.

FIG. 2 illustrates an exemplary tray table 104 having a portableelectronic device 204 installed therein. As can be seen, the portableelectronic device 204 may be held by the support 108 at a reclinedangle, such as described above. It is contemplated that the support 108may have a length selected to accommodate a variety of portableelectronic devices. For instance, as can be seen from FIG. 2, thesupport 108 may accept a tablet device but also is sized to allowsmaller devices, such as portable media players, smart phones, andportable gaming machines, to be held.

It is contemplated that the support 108 may be configured to provideconnectivity to any device it is holding. For instance, the support 108may have electrical, optical, or other terminals to provide power ordata connections to a portable electronic device. In some embodiments,the support 108 may provide wireless connectivity to power or dataconnections. For example, the support 108 may provide inductive batterycharging or a short-range data connection (such as a Bluetooth™connection) to portable electronic devices. The tray table 104 maycontain its own power source, such as one or more batteries, and/or maybe connected to an aircraft's power system. The batteries may berechargeable. In one or more embodiments, the batteries may be held in acompartment within the tray table 104 and be removable therefrom, suchas for replacement, recharging, or both.

As disclosed above, the tray table may provide an adjustable support insome embodiments, such as to permit passengers to position theirportable electronic devices at various angles. As will now be describedwith regard to FIGS. 3A-3C, the tray table 104 may include a rotatableassembly to allow such positioning.

FIG. 3A provides a top perspective view of the tray table 104. As can beseen, the outward appearance of an adjustable embodiment, may be similarto that disclosed above. In one or more embodiments, a control device304 may be provided to allow the position of the support 108 to bechanged. As shown, an adjustment wheel is provided as the control device304. It is noted that various control devices, such as knobs, levers,sliders, buttons, or the like may be used to move the support 108. Inaddition, multiple control devices 304 may be provided. For instance anadjustment wheel or other control device 304 could be on both sides ofthe support 108 in some embodiments.

It is also noted that the support 108 may be biased (such as by one ormore springs) in some embodiments. In this manner, the support 108 maybe configured to automatically move or rotate to a particular positionwhen a control device 304 is engaged, as will be described furtherbelow.

FIG. 3B provides a cross sectional view of the tray table across Line 1of FIG. 3A. As can be seen the body 136 of the tray table 104 may beconfigured to accommodate a rotatable assembly 308. For example, asshown in the embodiment of FIG. 3B, a compartment 312 comprising acurved front and back wall 316, 320 configured to accept the rotatableassembly 308 while allowing the rotatable assembly to rotate or movewithin the compartment is provided. The compartment 312 may include abottom 324 to enclose the rotatable assembly 308. An optional bottom 324may be provided in some embodiments. It is noted that without a bottom324, any dirt or debris that collects in the rotatable assembly 308 canbe removed by rotating the assembly such that such debris can fall outof the assembly. Alternatively, and opening 156 may be formed in thebottom 324 of the compartment 312 to allow such dirt and debris to exitthe assembly 308.

It is contemplated that the compartment 312 may extend from the topsurface to the bottom surface of the tray table's body 136 in someembodiments. In this manner, the compartment 312 would have an openingat its top and bottom. This allows electronic devices to be received inthe cavity 132 via the top opening of the compartment 312 while alsoallowing dirt and debris to exit the assembly via the bottom opening ofthe compartment. The body 332 of the rotatable assembly 308 may be sizedto protrude from both the top and bottom opening of the compartment 312.In this manner, the body 332 itself forms a seal with the compartment312 thereby preventing dirt and debris from entering the assembly 308.

The rotatable assembly 308 may comprise a body 332 having a cavity 132therein to accept a portable electronic device. Similar to above, thecavity 132 may comprise a front wall 140, a back wall 144, and one ormore sidewalls 148. A bottom 152 may be provided to prevent a portableelectronic device from falling out of the cavity 132, such as describedabove. As can be seen, the cavity 132 may be angled to hold a portableelectronic device at an angled position, such as described above. It iscontemplated that the cavity 132 may be not be angled (i.e., beperpendicular to the axis of rotation) in some embodiments. With therotatable assembly 308 for instance, a passenger may choose his or herdesired angle by rotating the rotatable assembly. Thus, the cavity 132itself may but need not be angled in all embodiments.

The body 332 or portion thereof of the rotatable assembly 308 may berounded or cylindrical in one or more embodiments, such as to allow therotatable assembly to rotate within the tray table 104. It iscontemplated that the body 332 or portion thereof could have other crosssectional shapes. For example, the body 332 may be triangular, apentagon, hexagon, or other shape. In some embodiments, the shape of thebody 332 may be used to help hold the body 332 in position after it hasbeen rotated. For example, the shape of the body may cause it to engageother surfaces of the tray table 104 thus holding the body in position.

One or more holding mechanisms may be used to hold the rotatableassembly 308 in a particular position. For example, a biased braking pador other surface may press against the rotatable assembly 308 (such asat the body 332) to prevent the rotatable assembly from rotating out ofa desired position. Other holding mechanisms, such as removable lockingpins, detents, or the like could be used as well. In addition, it iscontemplated that the body 332 may closely conform to its compartment312 to hold itself in position once rotated to a desired position.

FIG. 3C illustrates a cross sectional view of the tray table 104 acrossLine 2 of FIG. 3A. As can be seen, the rotatable assembly 308 maycomprise one or more axels 336 upon which its rotation may beaccomplished. The axels 336 may extend to engage a portion of therotatable assembly's compartment 312 to support the rotatable assembly308 therein.

As shown in FIG. 3C, an axel 336 may also be mechanically linked to acontrol device 304 in one or more embodiments. In this manner, the axel336 and thus the rotatable assembly 308 may be rotated by manipulating acontrol device 304. For example, in FIG. 3C rotating the control device304 also rotates the rotatable assembly 308. It is noted that one ormore biasing devices, such as springs, may engage or be attached to anaxel 336 as well. This allows the rotatable assembly 308 toautomatically move to a particular position when a biasing device isactivated. For example, a biasing device may be configured to rotate thecavity 132 of the rotatable assembly 308 such that it is accessible fromthe top of the tray table 104. Alternatively, a biasing device couldrotate the cavity 132 such that it is inaccessible, thus “closing” thesupport 108. This may be desirable to prevent unwanted dirt or debrisfrom entering the cavity 132, such as during food service on a flight.

FIGS. 4A-4B illustrate a rotatable assembly 308 in operation. As can beseen, the rotatable assembly 308 may rotate from the open position shownin FIG. 4A to the closed position shown in FIG. 4B. In the openposition, the cavity 132 of the rotatable assembly 308 is typicallyaccessible, thus allowing one or more portable electronic devices 204 tobe supported therein, such as shown in FIG. 4A.

When not in use, the rotatable assembly 308 may be rotated to a closedposition, such as shown in FIG. 4B. As can be seen, the cavity 132 maynot be accessible when in the closed position. As stated, this preventsdirt or debris from entering the cavity 132. In embodiments where thetray table's compartment 312 has an open bottom, the rotatable assembly308 may be rotated to empty any dirt or debris that may have collectedtherein. It is noted that the compartment 312 may have a removablebottom to allow this cleaning process to occur.

It is noted that the cavity 132 of the tray table 104 may be configuredto protect any portable electronic devices it holds. For example, in oneor more embodiments, the cavity 132 or portions thereof may be padded orbe coated with non-abrasive surfaces to prevent the cavity fromscratching or otherwise damaging the enclosure of a portable electronicdevice.

FIGS. 4C-4E illustrate another rotatable assembly 308 in operation. Ascan be seen, an elongated tab 404 extends from the body 332 of therotatable assembly. The elongated tab 404 may be an elongated member,planer structure, or the like which extends from the body 332. Inoperation, a bottom portion of an electronic device may be placed in thesupport 108 while an upper portion is propped up against (i.e., held by)the tab 404. This can be seen from FIG. 4C, which illustrates therotatable assembly 308 in an open position.

FIGS. 4D-4E illustrate the rotatable assembly 308 in a closed position.In one or more embodiments, the body 136 of the tray table 104 may havea recess 408 formed therein to accept the tab 404. In this manner, whenclosed, the rotatable assembly's tab 404 is positioned flush with thetop surface 112 of the tray table 104. This prevents the rotatableassembly 308 from obstructing use of the tray table and provides aplanar surface for placement of one or more items. In addition, as canbe seen from FIGS. 4D-4E, the tab 404 also encloses the compartment 312preventing dirt and debris from entering. A cutout or recess 412 may beprovided to allow the tab 404 to be lifted in some embodiments.

Though shown in a compartment 312 having a bottom 324, it is noted thata bottom need not be provided in all embodiments having a rotatableassembly 308. For instance, as described above, the compartment 312 mayhave an open bottom to allow dirt and debris to exit the compartment.Alternatively, one or more openings may be formed in the bottom 324,such as described above with regard to FIG. 3B, to allow dirt and debristo exit the compartment 312.

FIGS. 4F-4I illustrate another exemplary tray table 104 having arotatable assembly 308. FIGS. 4F-4G provide a back perspective view ofthe tray table 104. FIGS. 4H-4I respectively provide a back and frontperspective view of the tray table 104. As can be seen, the rotatableassembly 308 may be formed at the back end 120 of the tray table 104rather than inset from the back end as described with regard to theabove embodiment. The rotatable assembly 308 may comprise a body 332having a cavity 132 for receiving and securing a portable electronicdevice 204.

The body 332 may be an elongated structure having flat sides. Forinstance, as shown in FIGS. 4F-4I, the body 332 is a rectangular shapeextending laterally between a left and right side of the tray table 104at the back end 120 of the tray table. In one or more embodiments, a lip420 may extend from a portion of the body 332. As can be seen from FIG.4F, the lip 420 may extend from a top portion of the body 332 so that itforms a barrier to prevent items on placed on the top surface 112 of thetray table 104 from sliding off the back end 120 of the tray table.

The cavity 132 will typically extend along the length of the body 332,such as shown. In one or more embodiments, the cavity 132 may be anelongated opening configured to accept a portion of one or more portableelectronic device 204. As shown in FIGS. 4H-4I for example, the cavity132 comprises a rectangular opening sized to accept an edge or end of aportable electronic device 204. This secures the portable electronicdevice 204 within the body 332 and allows a user to use the portableelectronic device 204 without having to hold the portable electronicdevice.

Positioning the body 332 of the rotatable assembly 308 at the back end120 of the tray table is advantageous in that it allows the cavity 132to be exposed at the back end of the tray table. When the tray table 104is in a stowed position, it will typically be in a vertical orientationwith the front end 124 of the tray table being above the back end 120 ofthe tray table. In this manner, any dirt or debris in the cavity 132would automatically fall out of the cavity keeping the cavity clean andunobstructed. Maintenance or other personnel may then collect such dirtand debris from the floor of the aircraft.

One or more openings 156 may be at the bottom of the cavity 132 in oneor more embodiments to also aid in keeping the cavity clean. Typically,an opening 156 will extend from the bottom of the cavity 132 to anexternal surface of the body 332. This allows any dirt or debris thatenters the cavity 132 to fall out of the cavity keeping the cavityclean. FIG. 4G illustrates an exemplary opening 156.

FIGS. 4F-4I also illustrate operation of the tray table 104 as itsrotatable assembly 308 rotates from a closed position, as shown in FIG.4F, to an open position as shown in FIGS. 4H-4I. FIG. 4G illustrates therotatable assembly 308 in an intermediate position as it rotates betweenan open and closed position.

In the closed position, the body 332 of the rotatable assembly 308 formsa portion of the top surface 112 of the tray table 104. For instance, asshown in FIG. 4F, the top portion of the rotatable assembly's body 332is coplanar with the top surface 112 of the tray table 104. In thismanner, the rotatable assembly 308 does not obstruct or hinder use ofthe tray table 104 when in the closed position. A passenger is thereforefree to place items on the top surface 112 of the tray table 104 asdesired. For example, the passenger may place food service items such asplates, cups, and utensils on the top surface 112. As shown in FIG. 4F,an optional cup holding inset 416 is provided to receive cups or thelike. The lip 420 extends upward at the back end 120 of the tray table104 to prevent items from falling off the back end of the tray table.

When use of a portable electronic device 204 is desired, the rotatableassembly 308 may be rotated to expose a cavity 132. As can be seen, thebody 332 of the rotatable assembly 308 may be rotated such that thecavity 132 moves in an arc starting at the back end 120 of the traytable. FIG. 4G illustrates the body 332 having been moved from theclosed position of FIG. 4F. As the rotation of the body 332 continues,the cavity 132 moves upward thereby positioning the cavity to receive aportable electronic device 204, such as shown in FIG. 4H-4I. In thisopen position, the cavity 132 holds the portable electronic deviceupright for use. FIGS. 4H-4I respectively provide a back and frontperspective view of the tray table 104 with its rotatable assembly 308in an open position and holding a portable electronic device 204.

In one or more embodiments, the rotatable assembly 308 may be configuredsuch that the opening of the cavity 132 is positioned above the topsurface 112 of the tray table 104 when the rotatable assembly is in anopen position, such as shown in FIGS. 4H-4I. This is advantageous inthat the higher elevation helps prevent any dirt and debris that may beon the top surface 112 of the tray table 104 from entering the cavity132.

FIGS. 4J-4K illustrate side cross sectional views of the rotatableassembly 308 of FIGS. 4F-4I in operation. FIG. 4J shows the rotatableassembly 308 in a closed position while FIG. 4K shows the rotatableassembly in an open position. As can be seen, the cavity 132 is orientedtoward the back end 120 of the tray table 104 in the closed position,while the cavity 132 is oriented upward to receive a portable electronicdevice 204 in the open position.

As described above, the cavity 132 may comprise a front wall 140, a backwall 144 and one or more sidewalls 148. The bottom 152 of the cavity 132engages an edge or end of a portable electronic device to support theportable electronic device. An optional opening 156 at the bottom of thecavity 132 allows dirt and debris to exit the cavity, as describedabove. As can be seen from FIG. 4K for example, in the open position,dirt or debris that enters the cavity 132 would fall into the opening156 and out of the body 332. It is noted that dirt and debris that istoo large to fit into the opening 156 would fall out of the cavity 132when the tray table 104 is put in a stowed position, as described above.

The body 332 of the rotatable assembly 308 may be mounted to the traytable 104 via one or more rotatable mounts. FIG. 4L illustrates a backcross sectional view of the rotatable assembly 308 where the body 332 ofthe rotatable assembly is mounted to the body 136 of the tray table 104via a pair of axels 336. As can be seen, the axels 336 may extend fromthe left and right or lateral ends 424 of the body 332 and into aportion of the tray table's body 136 (or vice versa). The body 332 canthus rotate about the axels 336 between the closed and open positions,as shown respectively in FIGS. 4J-4K.

It is contemplated that some embodiments of the tray table 104 maycomprise movable or removable portions to allow for cleaning andmaintenance. Referring to FIGS. 5A-5C for example, a first portion 504of the tray table 104 may be configured to separate from a secondportion 508 of the tray table. at one or more separations 516. In one ormore embodiments, the two portions 504, 508 may meet at or near thesupport 108. In this manner, the two portions 504, 508 would beseparable at or near the support, such as delineated by Line 2 of FIG.5. shown. Once separated, access to an interior portion of the support108 is more easily achieved, such as to clean or maintain the support108 or any elements associated with the support (such as adjustableelements).

One or more fasteners 512 may be used to allow the first portion 504 andsecond portion 508 to removably attach to one another. For example, asshown, the tray table 104 may comprise one or more hinges that allow thefirst and second portions 504, 508 to fold relative to one another,thereby providing access to an interior portion of the support 108. Itis contemplated that the hinge may include a biasing mechanism and orlocking mechanism to hold the first and second portions 504, 508 in aplanar configuration (such as shown in FIG. 55A) during use. One or moreadditional fasteners 512 such as screws, pins, claps, magnets or thelike may also or alternatively be used to hold the first and secondportions 504, 508 in the planer configuration.

Alternatively, the first and second portions 504, 508 may be completelyseparable form one another, such as in the embodiments of FIGS. 5B-5C.For example, the first and second portions 504, 508 may be configured topull apart when detached from one another. In such embodiments, FIG. 5Cillustrates the tray table 104 having its first and second portions 504,508 separated from one another.

It is noted that the first and second portions 504, 508 may comprisemating surfaces or structures that secure the first and second portionstogether when connected. For example, the first and second portions 504,508 may have grooves, slots, tabs, or the like that correspond to oneanother. It is noted that, similar to Also, as stated above, one or moreadditional fasteners 512 may be used to secure the first and secondportions 504, 508 in a planar configuration. As shown in FIG. 5C forexample, one or more pins 520 may connect and secure the first andsecond portions 504, 508 together when assembled.

It is contemplated that, when mounted to an aircraft passenger seat,only the first or second portion 504, 508 would be attached to the traytable support arms of the seat. This permits the first and secondportions 504, 508 to be removable from one another (such as to clean ormaintain the support 108) without removing the tray table 104 from theseat. Alternatively, both the first and second portions 504, 508 may beattached to the tray table support arms, such as to secure the first andsecond portions together in a planar configuration. In such case,additional fasteners for holding the first and second portions togetherneed not be used.

FIGS. 6A-6F illustrate various slots or cavities 132 having biasingmechanisms 604 that may be used to help hold or secure a portableelectronic device 204. In general, a biasing mechanism 604 applies forceto a portable electronic device 204 to increase friction between theportable electronic device and a cavity 132 in which it has beeninserted. For instance, a biasing mechanism 604 may clamp or squeeze aportion of a portable electronic device 204 to help secure the portableelectronic device within a cavity 132. As can be seen from FIG. 6A-6F, abiasing mechanism 604 may be used in embodiments with a fixed support108 or rotating assembly 308, including those disclosed above.

FIGS. 6A-6B provide a side cross sectional view of a first biasingmechanism 604 in operation. As can be seen, a biasing mechanism 604 maycomprise a presser 620 that applies force to a portable electronicdevice 204 to help secure the portable electronic device. In theembodiment of FIGS. 6A-6B, the presser 620 is pivotally attached to thebody 132 of a tray table 104 at a mount 624 within a cavity at back end120 of the tray table via a connecting rod 616. It is noted that a pivotor rotating mount may attach the connecting rod 616 at either or both ofits ends. The presser 620 is biased or pushed into a cavity 132 of thetray table 104 by one or more biasing devices 612. This causes thepresser 620 to protrude into the cavity 132.

A presser 620 may also be coupled to one or more biasing devices 612,such as various springs, elastic or other resilient device/material. Avariety of biasing devices 612 are illustrated in FIGS. 6A-6B. It iscontemplated that only a single biasing device 612 is needed in mostembodiments however. It can be seen with reference to FIGS. 6A-6B that abiasing device may bias movement of a presser 620 at its pivot (e.g., ata rotating mount 624), at its connecting rod 616, or at the presser 620itself.

In FIGS. 6A-6B, the biasing device 612 directly connected to the presser620 expands to push the presser into the cavity 132, the biasing deviceconnected to the connecting rod 616 compresses to pull the presser intothe cavity, and the biasing device at the rotating mount 624 applies arotational force with rotates the presser into the cavity. It is notedagain that only a single biasing device 620 need be used in mostembodiments. The presser 620 may protrude into the cavity 132 through anopening 608 in the back wall 144 (or front wall 140).

As can be seen from FIG. 6B, when a portable electronic device 204 isinserted in the cavity 132, the presser 620 is forced at least partiallyout of the cavity 132 to allow the cavity to accommodate the portableelectronic device. In this position, the presser 620 continues to exertpressure or force on the portable electronic device 204 from its one ormore biasing devices 612.

FIGS. 6C-6D provide a cross sectional view of a second biasing mechanism604. As can be seen, the presser 620 in this embodiment is within thecavity 132 at a first wall 144 of the cavity. A biasing mechanism 612applies force to push the presser 620 towards the opposite wall 140 ofthe cavity. Alternatively or in addition, a biasing mechanism 612 may beat a pivot point of the presser 620 and apply rotational force at suchpoint to push the presser 620 towards the opposite wall. The presser 620is pivotally or movably mounted to a mount 624, similar to above. It isnoted that a presser 620 may move linearly rather than rotationally insome embodiments. For example, a presser 620 may extend and retractparallel to a front or back wall 140, 144.

As can be seen in FIG. 6D, when a portable electronic device 204 isinserted in the cavity 132, the presser 620 is forced back towards thefirst wall 144 to allow the cavity to accommodate the portableelectronic device. In this position, the presser 620 continues to exertpressure or force on the portable electronic device 204 from its one ormore biasing devices 612.

A presser 620 may be rounded, angled or both to prevent a presser 620from obstructing entry of a portable electronic device 204 into a cavity132. As can be seen in FIGS. 6A-6B for instance, the presser 620 isrounded and may rotate at the distal end of its connecting rod 616 toallow insertion of a portable electronic device 204 without obstruction.In the embodiment of FIGS. 6C-6D, the presser 620 has an angled distalend so as to also allow a portable electronic device 204 to be insertedinto its cavity 132 without obstruction.

FIGS. 6E-6F illustrate another embodiment of a biasing mechanism 604where the presser 620 forms one of the walls 140 of the cavity 132.FIGS. 6E-6F also show that a biasing mechanism 604 may be used inembodiments having a rotating assembly 308.

As can be seen, the presser 620 in this embodiment is pivotally ormovably mounted via a mount 624. A biasing device 612, such as a spring,is at the mount 624 and provides a rotational bias which forces or movesthe presser 620 towards the opposite wall 144 of the cavity. In one ormore embodiments, the biasing device 612 may be about or at a pivot oraxel of a mount 624 to apply rotational force to the presser 620.

As can be seen from FIG. 6F, the bias of the presser 620 is overcome asa portable electronic device 204 is inserted into the cavity 132. Thepresser 620 is moved outward to accommodate the portable electronicdevice 204 and continues to apply inward pressure or force to helpsecure the portable electronic device in the cavity 132.

Though shown at or forming a front wall 140 or back wall 144 of a cavity132 in FIGS. 6A-6F, it is contemplated that a biasing mechanism 604 maybe at either or both walls 140, 144 of a cavity. In addition, it iscontemplated that a presser 620 need not be pivotally or rotatablymounted in all embodiments. For example, a presser 620 may be mounted toa telescoping mount that moves in a linear inward and outward fashion. Abiasing device 612 can be used to bias the telescoping mount outward toapply force or pressure to a portable electronic device 204 wheninserted.

FIGS. 6G-6K illustrate another exemplary embodiment comprising arotatable assembly 308 and a presser 620. The perspective view of FIG.6G illustrates the rotatable assembly 308 installed in an exemplary traytable 104 and rotated to an open position. A portable electronic device204 is received within the cavity 132 of the rotatable assembly 308 andheld for use by a passenger or other user. A body 332 of the rotatableassembly 308 may be rotatably mounted to a tray table 104 via one ormore axels 336 (and openings 632 for receiving such axels), pivots orother rotatable mounts. Similar to above, the presser 620 is movable toreceive and hold a portable electronic device with a cavity 132 of therotatable assembly 308.

FIGS. 6H-6I respectively illustrate top and bottom perspective views ofan exemplary presser 620 in a retracted position, while FIGS. 6J-6Krespectively illustrate top and bottom perspective views of the presserin an extended position. As can be seen, the presser 620 may form orcomprise a front wall 140 and bottom 152 of a cavity 132 and be movable(i.e., extendable and retractable) therewith. A body 332 of a rotatingassembly 308 may comprise a notch 636 to receive a presser 620. It canbe seen from FIGS. 6H and 6J for example, that the body 332 comprises acentral notch 636 where the presser 620 is movably mounted.

In a retracted position the front wall 140 and back wall 144 are closerto one another as compared to an extended position. This allows a cavity132 to accommodate portable electronic devices of various widths. Also,a biasing mechanism 604 may apply a force to move the presser 620 (andtherefore the front wall 140) toward the back wall 144. This too helpssecure a portable electronic device within a cavity 132.

As can be seen from FIG. 6K, one or more biasing devices 612 may be usedto produce such force. In the embodiment of FIG. 6K for example, biasingdevices 612 comprising springs extend between the body 332 of therotatable assembly 308 and the presser 620. The biasing devices 612apply force causing the presser 620 to be biased to a retractedposition, such as that shown in FIG. 6I.

It is noted that a biasing mechanism 604 may include one or more guides628 to guide or control the movement if a presser 620. As shown in FIG.6K for example, one or more guide pins 628 extend from the body 332 andinto corresponding openings of the presser 620 to guide the movement ofthe presser as it moves between an extended and retracted position. Apin 628 may have an enlarged distal end to prevent the presser 620 fromextending beyond a predefined point. It is contemplated that one or moreguides 628, may be at the lateral ends of a presser 620 in someembodiments. For example, a linear channel may be formed in each lateralend of a presser 620 while corresponding rails extend from the sides ofthe notch 636 of a body 332, or vice versa.

In some embodiments, a biasing mechanism 604 need not be provided. Insuch embodiments, a presser 620 may be held in position by friction,such as between one or more pins 628 and their corresponding openings.Alternatively, one or more detents and corresponding tabs may be used tohold a presser 620 in position. For example, a detent or tab may beformed at the lateral ends of a presser 620 with a corresponding tab ordetent at a body 332 of a rotatable assembly 308.

FIGS. 7A-7B illustrate a side view of an exemplary tray table 104 havinga collapsible slot or cavity 132. As can be seen, a slidable or movablebracket 704 forms a back wall 144 and bottom 152 of the cavity, while afront wall 140 of the cavity 132 is formed by the tray table's body 136.The bracket 704 is slidable at a back end 120 of the tray table 104 toallow a cavity 132 to be expanded and collapsed.

For instance, the bracket 704 has been moved toward the tray table'sbody 136 in FIG. 7A. This collapses the cavity 132. In FIG. 7B, thebracket 704 has been moved outward from the body 136 to expand thecavity 132. Once expanded, a cavity 132 can receive, support and securea portable electronic device therein, such as described above. It isnoted that one or more biasing devices 612, such as springs, may pullthe bracket 704 toward the body. This bias applies pressure or force toa portable electronic device to help secure the portable electronicdevice once inserted in the cavity 132. Alternatively or in addition, itis noted that the back wall 144 may be formed by a presser 620, such asdescribed above with regard to FIGS. 6E-6F. In another embodiment, apresser 620, such as described with regard to FIGS. 6A-6D, may be at thefront wall 140 or back wall 144 of the cavity.

Typically, a bracket 704 will comprise a base 716 and an upright 712.The base 716 and upright 712 may be perpendicular to one another such asshown in FIGS. 7A-7B. Alternatively, the base 716 and upright 712 mayextend at various angles. For example, an upright 712 may be angledbackwards to allow a portable electronic device to be supported at areclined angle. It is noted that, in some embodiments, a portion of atray table's body 136 may have a notch 708 or removed to accommodate thebase 716 of a bracket 704. Alternatively a body 136 may have a slot orcavity therein to receive the base 716 of a bracket 704.

It is noted that a notch 708 need not be provided in every embodiment.For instance, in a retrofit where the bracket 704 is installed on apreexisting tray table 104 the bracket may be movably secured at abottom surface of such tray table. Alternatively, a notch 708 may bemachined or otherwise formed in the preexisting tray table 104.

One or more slides may be used to secure a bracket 704 to a tray table'sbody 136. A slide may comprise a rail, groove, or other structure thatallows a bracket 704 to move inward and outward to respectively collapseand expand a cavity 132. In FIGS. 7A-7D, slides comprising a peg 720 andrail 724 movably attach the bracket 704 to the tray table's body 136. Ascan be seen, the pegs 720 have an enlarged head at their distal ends.One or more narrower pins extend from the enlarged head and are securedto the body 136. As shown in the bottom views of FIGS. 7C-7D, the one ormore pins slide within rails 724 of the base 716 of a bracket 704, whilethe enlarged heads secure base 716.

In FIG. 7C, the cavity 132 is collapsed. The bracket 704 can then beslid outward to expand the cavity, such as shown in FIG. 7D. In anexpanded position, the front wall 140 and back wall 144 are sufficientlyseparated to accept a portable electronic device. Thereafter, a portableelectronic device can be inserted into the cavity. When no longerdesired, the cavity 132 can again be collapsed by moving the bracketinward towards the tray table's body 136. This reduces the size of thetray table 104 allowing it to be stowed in a more space saving manner.

While various embodiments of the invention have been described, it willbe apparent to those of ordinary skill in the art that many moreembodiments and implementations are possible that are within the scopeof this invention. In addition, the various features, elements, andembodiments described herein may be claimed or combined in anycombination or arrangement.
